Albert E. F. Moonefchicago, Ill., assig nor to, Orenda Corporation,Chicago, 111., a corporation of Illinois Application November 1, 1930.Serial No. 492,740. 10 Claims. o1. 154-3 1) The invention relates toapparatus formaking packing material and has reference in particular toa method and means'for forming packing material having super-cushioningproperties.

An object of the invention is'to provide a machine having improved meansfor efliciently forming a pluraltiy of grooves in a continuously movingsheet of paper longitudinally thereof, by

initially gathering said sheet" centrally of the same by forming offsetsin the plane of the sheetand subsequently utilizing the offsets to formthe grooves; to provide improved means including: a series of drums'tosuccessively form embossed areas on the sheet as it is received from thegathering rolls and to apply tothe side of'the sheet opposite theembossed areas a thin'coating of an adhesive; to provide'means includinga second series of drums to press together the embossed sheet and abacking sheet whereby the two sheets are secured together by means ofthe adhesive to form the packing material. Another important feature ofthe invention comprises the provision of novel means for receiving thematerial as it leaves the finishing drums and successively stripping thesame to'the desired width and cutting the same transversely into desiredlengths.

Another object of the invention is to provide a machine which willperform all of the above stated objects and in addition will includenovel mechanism for successively applying a coating of adhesive to asecond sheet provided with embossed areas and pressing said coated sheetinto contact with the backing sheet of previously formed material tothus form packing material having increased thickness with resultingincreased resiliency.

Another object of the invention resides in providing a method of forminga sheet in which the longitudinal grooves are formed progressively; inwhich the grooves are set in the sheet by heating the same prior toforming embossed areas in the sheet by simultaneously heating the rsheet and forming transverse grooves therein; in which the embossedsheet is joined to a backing sheet and simultaneously heated again toset the adhesive, resulting in the finished packing material.

A further object resides in providing a pair of drums having grooveforming members thereon for forming embossed areas in the sheet, andsucceeding pairs of drums with only one drum of each pair having thegroove forming members thereon, the cooperative drum of each pair beingplain.

A further object of the invention is to pro-- vide. amachine havingpairs of drums, certain of which have groove forming members thereonforsuccessively forming'nembossed areas in a sheet of paper and settingthe embossed areas while simultaneously applying the embossed sheetto'abacking sheet.

With theseandivariousfothen objectsin view, the invention may r 'cbnsistof certain 'novel features of I construction and operation as will bemore 'fully'. described 'rand particularly pointed out'in thespecification, drawings and claims appended'hereto. I 1

Figure 5 is a sectional diagrammatic-view of and a Figure 11'is afragmentary perspective view showing the'surface of the female formingdrum.

The machine of the present invention is particularly useful inconstruction of packing material such as shown in detail in Figure 8,for packing fruit, radio tubes and other fragile articles, and also eggsfor shipment, it being desirable in packing the latter to employsectional dividers in connection with grooved sheets or fiats, each eggwhen packed being located in contact with a fiat or embossed area andbeing separated from adjacent eggs by the sectional dividers which havelocation in the grooves. The present invention contemplates a method andapparatus for continuously forming packing material of the kinddescribed from rolled paper stock of a relatively inexpensive grade andfurther contemplates forming packing material of a modified form, moreparticularly illustrated in Figure 9, which consists in the flats orembossed areas extending from both sides of a backing sheet, the producthaving a substantial increasein resiliency and cushioning effect due tothe additional embossed area.

ing a sheet 10 having longitudinal grooves l1 and transverse grooves 12Illhe materialgof grooves il'and transverse grooves 12 asrat 16 and 17respectively. In Figure 9 a slightly modified form of'material is:shownin which the sheet 10, in combination with the hacking sheet 15,has

secured thereto an embossed sheet 20, the embossed sheet 20 havingcontact with'thebacking sheet .15 at points 18 and correspondingrespectively to the longitudinal and; transverse grooves of the embossedsheet .20. Packing material constrnntedas above has the advantage ofincreased resiliency-and resulting cushioning efiect'by reason of theadditional embossed areas-on sheet Such material .finds'manyuses,especially is the same useful unpacking-eggs, .since it can be used as adividing-partition, eggs having contact with the. raised areas of sheet-10 and other eggs in contact' with :the corresponding areas of sheet20.

Referring more particularly to Figures 1 and 2, the machine is locatedupon any suitable base 21 having uprights 22, .23 and'24 securedthereto. Side frames 25 .and 26 are in turn supported from the uprightsand held in spaced position by means of any suitable transverselyextending tiewbars.

Located. upon the frames 25 and 26 centrally thereof are water tanks 27,thetanks supported a suitable distance above the frames and serving as areservoir for supplying water to a number ofpipes 28. The tanks areprovided for the purpose of cooling the bearingsand journal,

boxes of the various drums and rolls to be later described, sincecertain of these drums are electrically heated and in order to providefor efficient operation of the same, zitis necessary to provide acontinuous flow of cooling water to maintain the trunnions at a moderatetemperature.

At the feeding end of the machine, Figure 1, is located a plurality ofstands 30 for supporting-a roll of forming paper 10 and a roll ofbacking paper 15. Each stand is provided with a suitable journal bearing33, divided centrally thereof forming a member 31 pivoted at 32, theparts being held in operative position by means of winged nuts 34. Therolls of paper stock are supported on shafts 35, the shafts in turnhaving engagement in bearings 33 and. by reason of the construction ofthe bearings the shafts can be removed and :s'moilar shafts having a newroll of paper thereon can be substituted therefore. Upon the base-21 issupported an idler roller 3'? under which is passed the paper -.fromrol-l 15, while secured to stand v22 is aplurality of idler rollers 38underwhich passes the paper from roll 10 and from which it is run in-asubstantially companion rolls 52, 5 3, 5.4:and55.

vertical direction between anumber of steam pipes 40 from small openingsin which issues live steam, so that the same is directed against thesurface of the paper. Located below the idler rollers 38 is a drip pan41 which collects the moisture of condensate resulting from the acondensation of the steam due to its contact} with the paper. The papersheet secured from roll 15 comprises the backing sheet of the material,while the paper from roll 10 comprises the embossed sheet and thislatter, prior to forming the same with embossed portions, is passedthrough In Figure 8 the material is shown as compr'is--- a plu-rality ofgathering rolls, which will be described.

' lIhe paper ldafter. passing between the steam pipes 40 tosuitablymoisten the same, is directed over a heating roll 42 journaled at theextreme right handendof'the frames 25 and 26. As

shown in Figure 3, the roll is suitably heated by means of a length ofresistance coil located within the roll, :thecurrent being conducted tothe resistance-coil by means of connector rings 43. For receiving thepaper from the roll 42 and for functioning as pressurerolls forsqueezing the excess moisturewfromthe paper, are a plurality ofcooperating rolls 44 and 45, the'upperroll '44 being-provided withaqgroove 46, while the-lower roll is provided. with a*bulge.-47-cooperating with the groove. Located in advanceof rolls44 and areaplurality-0E forming-walls 48, 49, 50, 51, etc; which -have=-cooperative-relationship with The, rolls 48, 49,50 and 5 1 .are .driven--i-n aclockwise direction and-for thegjpurpose are providedwith suitabletrunnions=to which are-secured gears. 56-.- The rolls-52;,53; 54 and55=are driven in a counterclockwise direction by means ofgears 57secured to thetrunnion-of the same, as shownin Figure 1. Shaf-tAB- isprovided withshoulders 58 and 59, which cooperate with similar shoulders60 providedonshaft 52. These shoulders are disposed-man offset relationas -shown in Figure l, so that as asheet passes between the rolls 48 and52, agathering of the stock occurs at the center: thereof .in the,formation-in the sheet of offset portions which ,are subsequentlyfinally formed into grooves.

The-precedingrolls 49 and 50 are also formed with-shoulders 62, whiletheir companion rolls 53 and .54 are provided with similar shoulderswhich cooperate with 62' in the same manner as described inconnectionwith roll48 and 52. Also provided on .rolls 49 and 56 arebeads 63 and 64 which have engagement with grooves 65 formed in thecompanion rolls 53 and 54. These beads are arranged substantially inalignment with shoulders 58 and 59 of the preceding roll and finallyform the ultimate inside grooves of the sheet in a manner to utilize thestock offset by the shoulders 52 and 53 as previously brought out. Uponthe succeeding roll 51 are formed similar beads-66 andshoulders 65, thebeads being aligned withbeads 63 and 64 so that they function to retainthe shape of the grooves finally formed by the latter beads. Theshoulders 65 function to form additional offsets in the plane of thepaper, which are subsequently finally formed into grooves by means ofthe beads on succeeding rolls. The gathering of the sheet of papertherefore occurs with the forming therein of a groove by means'of thebulge 4'7 and groove 46, which initially gathers the stock withoutgiving thereto my definite formation. By reason of the shoulders 58 and59 offsets are formed in the stock which are subsequently finally formedinto grooves; It is thus seen that, as the paper passes through thegathering rolls, the same is formed with grooves progressively beginningfrom the center of the sheet and continuing to either side thereof whenit is subsequently submitted to further forming mechanism, to bepresently described.

The rotation of the gathering rolls is accomplished by means of gears 56provided on the upper rolls, which have meshing engagement with gears 57provided on the lower rolls. Located between gears 57 are idler gears68, which have meshing engagement with adjacent gears 57 so that all ofthe upper rolls, namely, 48, 49, and 51 are driven in a clockwisedirection and at the same speed, while the lowersrolls 52 to 55inclusive are driven in a counter-clockwise direction at the same speed.By means of meshing gears 68 and 69 secured to roller 44 and 45respectively, the same are driven in the desired rotation and inaccordance with the rotation of the forming rolls.-

The sheet upon leaving the forming rolls next.

'aside frames provided therefore. All four of the drums 70, 71, 72 and73 are provided with a heating device comprising a resistance coil 75which is located and rigidly supported within the drum. Connector rings76 are provided for furnishing the resistance coil with a continuoussupply of electric current, the rings being suitably secured to thetrunnions 74 and having connection to the coil through openings 76. Thedrums 70 and 71 are provided with meshing gears 78, which by means of asuitable idler pinion, is driven in accordance with the rotation of thegathering rolls. Drums 72 and 73 are also provided with suitable drivinggears 79 having meshing engagement to each other-and adapted to receiverotation from a main driving gear 80.

Drum 70 is'formed with a plurality of beads 81 which cooperatewith'corresponding grooves 84 formed in the drum 71. It is to be notedthat these beads and their corresponding groove allow the drums toreceive the paper as it leaves the gathering rolls and permanently setthe plurality of grooves previously formed therein. Referring to Figure10 the surface of drum 72 is shown as provided with a number of annularbeads 82, which are in substantial alignment with the annular beads 81on roller 70. Intersecting beads 82 are a plurality of transverselyextending beads 83, the annular and transverse beads formingindentations in the surface of the drum. The drum 73 has a formation forcooperating with drum 72 and is formed with annular grooves 85, Figure11, which are intercepted by a plurality of transversely extendinggrooves 86, these grooves resulting in a series of raised portions uponthe surface of the drum. As previously stated drums 72 and 73 are heatedso that, as the paper is passed between the rolls the longitudinalgrooves formed therein are still further set by means of the beads 82and groove 85, while the paper in addition is formed with transverselyextending grooves by means of beads 83 and grooves 86. By firstconstructing the longitudinal grooves and then the transverse grooves ina manner as disclosed, the paper at no time is under tension and thedanger of fracturing or tearing is entirely eliminated.

By reference to Figure 1. it is seen that both the forming rolls and thegathering rolls are driven in accordance withtherotation of the maindriving gear by means of the idler pinions described so that a sheet ofpaperinserted between drums 44 and 45 will be continuously fed to thegathering rolls and from the gathering rolls will be fed to the groovingand embossing drums with a uniform speed, so that no tearing of thepaper nor undue strain is placed upon the same.

The next step in the operation of the machine is tov apply to thesurface of the embossed sheet a coating of adhesive which'isaccomplished by suitably journaling, in the ,side framesa plain surfaceroll 95, Figure 2, having cooperative engagement with a plain surfaceroll'96. The drums are suitably-mounted in the side frame; by means oftrunnions 97 and are adapted to be driven by gears 98-having meshing.engagement witheach other,

- which in turn are driven-afrom ro1l;:73 by means of pinion 99.Locatedunder roll 96'and extending the entire width of the roll is a pan100 for containing a supply of adhesive such as-sodium or potassiumsilicate,the pan being so located in relation to roll 96 that a portionof the roll will be immersed in the adhesive. Located adjacent the roll96 is a scraper 101', which is spaced a slight distance from theperiphery of the roll so that the surplus adhesive carried by the rollwill be removed-and allowed tov drop back into the pan. The paper as itleaves the embossing roll 72 and 73 is fed between rolls 95 and 96,which results in coating the bottom surface of the sheet with anadhesive, the bottom surface however, comprises merely the grooves 11and 12, since the; sheet is provided with the embossed areas and thegrooves are the only part of the sheet designed to engage the backingsheet. The next operation is therefore to bring in contact with theembossed sheet a backing sheet, and this operation will be nowdescribed.

As shown in Figures 2 and 4 a second embossing roll is providedincluding drums 102 and 103,

each having a cooperating plain surface roll 104 and 105 respectively.Also associated with the embossing roll 102 and its plain surface roll104 is a second plain surface roll 106, the latter rolls functioning topresent to the-embossed sheet the backing sheet 15. The drums 102, 103,104 and 105 are provided with suitable trunnions 107 and by means ofadjustable journal boxes 108 are journaled within the side frames 25 and26. These rolls are also heated in a manner as described in relation torolls 72 and 73 by means of a length of resistance coil 109 locatedwithin the drum and supplied with current by means of collector rings110, secured to the trunnions described. By means of gears 111 securedto the drums the same are driven in unison by reason of the idler pinion112 having meshing engagement with gear 98 and pinion 113, which hasmeshing engagement with adjacent gears 111. The drum 106 respectivemembers 132 at'l45.

is also :driven. bydhe --'desire'dtspeedf::as'gear .114 has meshingengagement with the corresponcv ing' gear 111 on'the'drum .104.By'referring'to Figure 5 it will .be;seen .that'thebacking paper15 isrun over .rollersflintil the same is presented-to roller 106 whichprovides a smooth surface ."for taking out any creasesin the paper andfor subsequently presenting-the same to drum-104 where thesame isbrought into contact with theembossed paper .10 to'which' hastbeen-applied thecoating of adhesive as "described; By mean's of 1 theheat in the drums'1ll2;.1='03; 104-and 105' Ire- I spectively, theformation of the embossed areas 01 thelpaper is finally set,- and'iniaddition "th'e 'ad-f hesive is dried so that its adhering-- qualitiesare materially.increased,"whereby,' when the material: leaves rolls 103and 1105; the sheets willbe securely' united, thepacking- "material.having'a form r as shown in Figure '8. 'For'stripping the material intodesired widths cutters 115 are 'employed and mountediupon transverseshafts 116and'117 suitably journaledtin the side 'frames.- Pinion 118"meshing with gear 111 serves: to drive'shaft 117 which turndrives-.shaftii 16' by means of-meshing pinions 120 secured' tothe'sh'afts respectively.

Members1-32 are'joined bytrans- 1 verse-shaft 133which suitably spac'es'themembers' and which foi'ms a mounting for'a'rms '134 to which are seoured'a' cutting blade-135. "Referring againtoarms 128* it is 'seenthat th samea'ie" connected" at their upper endto links'136 which are pivotally connected at- "137: t'o"'tliesli'dable' members 132, resulting in an actuation of the members '132 inaccordance with movement of arm 128. This'armis in turn" actuated by'cam125 and the movement is such that the members 132 are re'oiprocated uponthe bearing surfaces 131 formedin the frames 125'and 126.

Bearings 140 formed integrally with members 132 provide a mountingforatransverse shaft 141 to which is "secured a cam 142. The cam isadapted to engage a pin 143 provided on arm 144, the arm being in turnpivoted to oheof the Suitable linksf 146 and 147 serve to operativelyconnect the arm 144 to the shaft 133 journaied upon the slidablemembers. Rotation of shaft 141 is accomplished I by providing the shaftwith a suitable gear and connecting the same to shaft 124 by means of abelt 150.

As the finished material leaves the cutters 115 it'is' presented toretarding rolls 151 and 152 suitably journaled within the side'framesand-driven by means of gearing from the cutter shaft 117. For adjustingthe spacing of theretarding rolls' a member 153 is provided mountedinthe side' frames and functioning to adjust the-vertical traveling in-syhchron'ism readers height of the upper retarding roll by means'ofmaterial. Depending from the members 132 and .positioned 'level with the-endless'tapes 156 is a block 157 provided in its upper surface with asecond cutting blade 158 for cooperating with cuttapes functioning as asupporting means fdr' the" ting blade 135 to cut'the packing materialtransversely. The packing material in out form drops to a table 1 60supportedby'means' of a leg 161-, the table providing abearingfortheshaft 162. Endless tapes 1 63 are mounted on shafts 162 "and 155, thelat'terbeing-driven by belt 159 from asuitable pulley located'on shaft154. The 'table 160 therefore forms: a delivery mechanism for presentingto 'the operator individual sheets of the material 165' out to'thedesired lengths.

The members 132 have reciprocating movement and in one direction, travelagainst the direction of traveI 'of the packing material,"=but in their"return movement the member's travel at a rate of speedsubstantiallyequal tothat' of the packing material. The pivotal movement of shaft 133to -pause i the 1 cutting movements of 'blade" 135 is so tii'nedthat-with the members132 traveling towardsthe -right,Figure 2; the blade135'Wi11 be disengagedrflohi' blade-158; but"as"the= members 132 i begintheir travel: towards "the left' blade 135 travels" downwardlya'sthehigh part of cam 142 engages pin 143'an'd the movementof blade1'35 continues fuhti'l the travel towards the left of members "132 issubsta-ntial1y completed. It is thus seen that-engagement of blade 135with blade 138 wiIl out the materialtrahsversely without-causingbuckling oflthe material, since the cutting is accomplished with themechanism with" the travel of the packing material;

Referring 'to Figur 6 a modified 'formo'f mechanism fo'r'mak'ing-packing material is disclosed, comprising a 'seriesof form'ing'rolls 2'44; 248, 249, etc.', which "operate asdescribed and whichpresent the sheet to-a'series of forming drums and embossing drums 2*10ahd'272, respectively. In

advance of'the drums are a'plurality' of plain surface drums 295 and296, which cooperate with a. and is fed over rollers to a'pluiaility ofdrums 300 and "501 the latter drum operating in "conjunction with-a pan302 containing'sui'ta'ble adhesive such as sodium or potassium silicatefor applying to the undersuriace of-theembossedsheet 20 a thin coatingof adhesive. As previously explained, with the preferred modification abacking sheet 15 is-employedwhich is 'run over suitable rollers locatedin positionfor' presenting the sheet to suitable mechanism for bringingthe same into contact with'the previously embossed sheet to unite thesame together into the finished packing material. With-the apparatus asshown in Figure 6 the backing sheet 15 is run over roller 303 andpresented to a plurality of cooperating embossing drums 202', 203, 204and 205. These embossing drumsare of the same form'and character as drum72 previously described, having annular beads provided {on 'theperipherythereof with transverse'intersecting beads forming the surface of thedrum into a plurality of depressed portions. These depressed portionscooperate with the embossed areas on the sheet 10 and the sheet 20 andpress the same into contact with the backing sheet 15. As the embossedsheets have previously been coated on the proper surface with adhesiveuniting of the three sheets takes place, thus forming the completedpacking material, as particularly disclosed in Figure 9.

The usual form of mechanism for cutting and stripping the material isembodied in cutting rolls 220 which cooperate with retarding rolls 251and 252 to present the material to' the transverse cutting mechanismincluding the cutting blade 235.

It is to be understood that I do not wish to be limited by the exactembodiment of the device shown, which is merely by way of illustrationand not limitation, as various and other forms of the device will ofcourse be apparent to those skilled in the art without departing fromthe spirit of the invention or the scope of the claims.
